◆ UpdateCursorPosition()

bool CursorVars::UpdateCursorPosition	(	int	x,
		int	y
	)

Update cursor position on mouse movement.

Parameters

x	New X position.
y	New Y position.

Returns: true, if the OS cursor position should be warped back to this->pos.

Parameters

delta_x	How much change in the X position.
delta_y	How much change in the Y position.
